<p class="MsoNormal"><span style="mso-fareast-language:EN-US">This could be also related to the speed (Call Attempts Per Second - CAPS) that you are making the outbound calls. If you slow down the outbound calls being made and increase their duration does
this increase your simultaneous calls?<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">My guess is similar to your one that this is a provider issue. I know BT in the UK restrict the CAPS on their SIP Trunks to avoid network errors (or basically their SBCs cannot handle more CAPS).

<div>
<p class="MsoNormal">We got NORMAL_CIRCUIT_CONGESTION error trying to perform 100 simultaneous calls, and only 40 simultaneous calls actually happen (all other fail with NORMAL_CIRCUIT_CONGESTION). We have 1gbit/s network, all default rtp ports are open, and
<a href="http://switch.conf" target="_blank">switch.conf</a>.xml sessions-per-second=1000 (most freeswitch and gateway configs are default). We run dedicated server. Provider tell that 500 lines are available. Is it possible that I missed some config that could
limit gateway channels, or this is definitely provider issue?<o:p></o:p></p>
